Invalid date test feed

This is what happens (Akregator 5.10.3):
In Akregator::Feed::appendArticles fetched items are processed. All items are
stored in the feed's archive. Only new items which have a publication date
newer than the expiration date, will be appended to the feed's article list.
The next time the feed is fetched, all items which were processed earlier but
were not added to the article list and haven't changed since then, will be
processes as new items. That's when the problems start on these two lines:
 Article mya(*it, this);
 mya.offsetPubDate(nudge);

The (private) constructor of Article creates an object with an invalid
publication date (the default QDateTime constructor) because the item was
already stored in the feed's archive and it hasn't changed. On the next line
the publication date is updated, but based on the invalid publication date.
This causes the invalid date to be written to the feed's archive.

It's easy to reproduce with the attached feed:
1. Add the feed to Akregator.
2. Fetch the feed.

The article first appears as a blank line, but after restarting Akregator the
invalid is shown.
